Advantest Q8326 Overview
The Advantest Q8326 is an optical wavelength meter capable of high-accuracy and high-resolution measurement at the central wavelength of the light from laser diodes (LD) for DWDM. Using a He-Ne laser as the reference wavelength and the Michelson interference method for measurement, the Q8326 assures a high-accuracy measurement. The Q8326 even provides a high sampling rate of 5 times per second, and is suitable for adjustment of oscillation wavelength from laser diodes for DWDM. Wavelength variation can also be measured with high resolution and high accuracy using a deviation display function.
